本文以笔者研究组多年研究结果为基础,以玉米为主要参比作物,就干旱逆境下高粱的产量表现、水分利用及抗旱特性进行了论述。认为高粱是一种综合抗旱能力很强的作物,尤其具有低耗水、高水分利用效率特性,其耐旱性显著高于玉米,也高于谷子和苜蓿,属于一种典型的模式抗旱作物,具有重要的生产和研究价值。指出高粱作为抗逆性很强的粮饲酿兼用作物,特别是作为一种能源植物,仍具良好的发展前景。建议今后在降水量低于450mm、热量可满足生长的地区扩大高粱种植面积,同时加强对其整体抗旱性机理及抗旱基因组的研究。 Based on the results of many years’ study by our research group and corn as the main reference crop, this paper discussed the yield performance, water use and drought resistance of sorghum under drought stress. It is considered that sorghum is a kind of crops with strong drought resistance ability, especially with low water consumption and high water use efficiency. Its drought tolerance is significantly higher than that of corn and millet and alfalfa, Has important production and research value. It is pointed out that sorghum still has good prospects for development as a food plant with high stress resistance, especially as an energy plant. In the future, it is proposed to expand the planting area of ​​sorghum in areas with less than 450mm of precipitation and caloric growth, and at the same time to strengthen its research on the mechanism of drought resistance and drought resistance genome.
